What You Need to Know about RCA Signal Cable

One of the most common wires used today is the RCA signal cable. When setting up a stereo system, you are most likely to encounter this type of connection. It is important that you know its uses, as well as why you need to purchase high-quality signal cables.

What is a RCA Signal Cable?

RCA signal cable got its name from the company that invented it. It is designed for use in audio equipment. While they can also be used to connect a VHS deck to a television set for viewing, it can’t be used for serious video applications.

In technical terms, the RCA signal cable is used to transmit line level signals. Line level signals are weak signals that are transmitted from an audio device such as a DVD or CD player to an audio receiver.

Signal cables have metal plugs on both ends. There are usually two cables for every audio component so that there is one for the right channel and the other one for the left. This type of cable is colour-coded as black and red.

Hi-Fi cables are often shielded and have unbalanced line. They are used by audiophiles for their setups that don’t have a balanced line.

RCA signal cable is used to connect older audio players that don’t have an optical fibre or HDMI cable. When it comes to signal cables, consumers should be aware of the factors that affect the quality of the signal that include the cable length and materials.

Connector Material of RCA Signal Cable

One of the factors that can affect the quality of the signal is the connector. While the shape of the connector is standard, the materials used do vary from one signal cable to another. Materials have different conductive properties and can influence the quality of the signal. Some of the commonly used materials for connectors include copper, silver, and gold.

Silver is the best material in terms of electrical conductivity. It is followed by copper and gold. However, gold is used in areas where oxidation is a problem. Gold doesn’t oxidise, which means there will be no problems in signal transmissions due to oxidation. While there are no solid gold or silver connectors on the market, you can buy copper connectors that have gold or silver plating.

Signal cables with gold connectors are more expensive compared to the cables with copper or silver connectors. It is important not to overpay for a cable just because of its gold connectors. Consumers should also consider the other factors that include length and shielding of the RCA signal cable.

Length and Shielding of RCA Signal Cable

The longer the cable, the worse the signal will be. That’s why consumers should not buy a cable that is longer than what is required. And when it comes to shielding, a well-shielded signal cable can guarantee good quality signal because it can block out outside interference.

RCA signal cable has been around for ages and has various uses. When purchasing signal cables, it is important to know the different types of cables and how they are colour coded. It is important that consumers choose the right signal cable that suits the task. Find more information about signal cables here.
